How is an essay different from a research paper? Research papers go into greater depth on a specific subject, and they are more focused on the ideas surrounding that subject. Essays explore ideas. They are more classical in form, and many instructors still prefer an Introduction with a clear thesis, three supporting paragraphs, and an insightful conclusion to bring it all together. If you have this, then you usually have a great score. That being said, they are also looking for some wit or charm in the writing or ideas and the usual correct grammar, spelling, and punctuation. If you have all of these things, then you have no worries!
